TAILORS SQUARE.

SPECIFICATION forming part of Letters Patent No. 247,339, datedSeptember 20, 1881.

Application filed March 29, [881. (No model.)

To all whom it may concern Be it known that I, WILLIAM H. GoLns- BERRY,of Nevada, in the county of Story and State of Iowa, have invented animproved drafting-square and method of applying, adjusting, andoperating graduated scales in drafting garments, of which thefollowingisa specification.

The object of my invention is, first, to facilitate the draftingofcoats, pants, vests, dresses, and all kinds of garments that can bemarked out, out, and fitted by actual measurement; sec 0nd, to provide ameans for folding the two arms of a square into parallel position, forthe purpose of packing it more compactly and handling and preserving itwhen not in use.

It consists in permanently and adjustably connecting two slotted armstoform arightangle and square by means ofarigid strap that constitutes aninvariable hypotenuse and brace in the square, in such a manner that theoverlapping ends of the two arms at the angle or corner, of the squarecan be readily locked togethcr by means of a thumb-screw to produce arigid square, to which graduated scales can be successively attached andadjusted from one arm of the square to the other in forming scales insuch a manner as to be adapted to be used in combination with theimproved square, all as hereinafter fully set forth.

Figure 1 of my accompanying drawings shows my square in an invertedposition and its two arms folded in parallel position, as required forconvenience and safety in packing and shipping, and in placing it in adrawer when not in use. Fig. 2 is a top view, showing the arms extendedatright angles to each other and rigidly locked together and braced, asrequired for practical use. Fig.3 represents one of a series ofgraduated scales designed to be used in combination with the square.Fig. 4. is the diagram of the frontpart of a vestdrafted by means of myimproved square and oneof myadjustablescales. Jointly/considered,thesefigures clearly illustrate the construction, operation, and utility ofmy complete invention.

A is the long arm of my folding square. It is preferably made of hardwood, twenty-four (24) inches in length and about one (1) inch in width.At its inner and square end it is about one-fourth of an inch thick, andhas a square shoulder formed thereon on its top side, adapting it tooverlap and engage the corresponding end ofa short arm, as required toproduce a rigid right-angled joint.

Bis the short arm, preferably abouteighteen (18) inches long andthree-fourths of an inch tion of the arm A.

i is a longitudinal slot in the outer portion of the arm B. Theedgesofthesesloiis are rabbeted on their under sides to allow the heads ofshort screw-bolts to traverse them while. the

square lies flat upon the drafting-table, as re-' quired to move saidbolts k in said slots relative to the ends of the scales that are to befastened to the arms of the square.

m is one of my series of graduated scales, adapted to be adjustablyconnected with my folding square. They are preferably made of thinstrips of flexible hard wood and a complete scale is marked on each sideof each piece by means of dies,types, or in any suitable way.

It has a perforation, r, at the end designed to.

be pivoted to the corner of the square by means of the thumb-screw d,that connects and locks the ends of the arms A and B together. It alsohas a notch, s, at its opposite end, that allows a sliding screw-bolt,k, to engage the scale in such a manner that a thumb-nut, w, on the endof the bolt can be turned down to clamp the scale to the slotted arm ofthe scale, as shown in Fig.2. By means of the slots in the arms of thesquare,the notchesin theends of the scales, and the sliding screw-boltsin the said slots, scales of different lengths can be readily fastenedto the square, and also, when pivoted at the corner of the square,readily adjusted from one arm to the other, as frequently required indrafting garments, and as indicatedby dotted lines in Fig. 4.

In the practical operation of my invention, I take one of my series ofgraduated scales, that corresponds in number with the breast-measure orcircumference of the person for whom a garment is to be drafted, andattach it to the long arm of the square. For example, to draft a vest tofit a boy that measures twenty-four (24) inches around his breast, I usethe scale marked 24 acrossits end. I place the square, with the scaleattached, on the cloth upon which I wish to form my diagram, as directedby a pattern-sheet, in such a manner that the outside edge of the longarm will rest upon and be parallel with the edge of the materialinsideof the selvage, and the short arm Will extend laterally over the samematerial. I then draw a line along the outside edge of the square. On abase-line thus obtained I locate and mark the points designated by thepattern-sheet by means of corresponding numbers on the scale. When apoint and number higher than is to be located and marked the square canbe readily shifted to start again at the point 10, where the scaleended, so that any number and point. varying between 10 and can belocated by means of the same scalein the same direct line. To mark orlocate a number and point higher than 20, the square can be againadvanced along the same line to the point marked 20, and any point andnumber varying between 20 and located by means of the same scale; andwhen all the various points on the edge of the pattern-sh eet are thuscopied,

located, and marked along the edge of the cloth,I loosen the notched endof the scale and turn it on the pivotal screw in the corner of thesquare from the long arm to the short arm that extends across the cloth,and use the same scale for locating and marking the various pointsrequired to be made relative to the baseline and the points previouslymarked on that line, as illustrated by Fig. 4, and as commonly practicedin the art of drafting garments by means of scales.

Each one of my series of graduated scales is divided into ten (10) equaltenths and fractions thereof. Scales consisting of an equal number oftwelt'ths or other equal divisions may be used in combination with mysquare.

I claim as my invention- 1. The improved drafting-scale composed of thelong arm A, having a slot, h, and ascre\v seat, g, the short arm B,having a slot, i, and

perforation f, the pivoted strap and brace 0,

the thumb-screw d, and the sliding screw-bolts 70 w, substantially asshown and described, to operate in the manner set forth, for thepurposes specified.

2. The adjustable scale mrs,in combination with the scale A B, havingslots h i,a thumbscrew, d, and sliding screw-bolts 70 w, substantiallyas shown and described,to operatein the manner set forth, for thepurposes specified.
